Dear Wu,

It's glad to see you here. I got to know to through the Google Summer
of Code.

Well, as you've installed MINIX3 on a raw machine. I do not think it's
neither comfortable nor convient for you to do any development. I
strongly suggest you to use some virtual machine :-)

You can use "ifconfig". It's even easier than using it on a Linux box
because it's a simplified version.

If you're using GRUB, you can easily modify the configuration file at
"/boot/grub/menu.lst ". In fact, it's the menu list config file of
GRUB. The wiki page on the official website has already had this
concise guide. You just need to add the following lines to "menu.lst".

1. title Minix
2. rootnoverify (hdX,X) # (hdX,X) is the disk and partition where you
install Minix
3. chainloader +1 # tells GRUB this is another boot loader
4. boot # go, go, go

BTW, "d0p2" is used by MINIX3. It's not the right argument for GRUB.
The MINIX3 partition name on your hard disk is probably "hd0,3" since
you said it showed "(hd0,3) unknow file system 0x81" when you type
the command in GRUB.

I hope it can help.

PS: I'm a Chinese guy too.

Best regards,

Hi Sean Bray,

I am so glad to know you are Chinese! Would you mind talk via gtalk?
can we talk in Chinese here?

Thanks for the grub. It works now! I just learned grub today, and
added minix like : root kernel boot, like linux. I didn't know minix
is so different. For the network, I will try it tomorrow.

My mentor advices me to install minix on raw machine. Because I have
to do much efficiency test. Besides, I also prefer to run an OS on raw
machine, which helps you to learn it quickly. Maybe it's also
necessary to install one on virtual machine, because of the
development. In fact, I have tried to install minix3 on VMware, but
failed, which is talk at: http://groups.google.com/group/comp....085fff7afc61c9.
I also downloaded the pre-install minix in vmware from the minix3.org.
It works well.

Thanks
Wu

Minix creates 3 subpartitions inside one of the primary partitions of the
hard disk. Because Linux is aware of the Minix file system (it was the
original file system for Minix before EXT was developed), it recognizes
these subpartitions and created the /dev/sda5, /dev/sda6 and /dev/sda7
files for you to mount. However, GRUB is not as sophisticated and does not
recognize the Minix subpartitions, only the root partition. Hope this
clarifies something

Regards,

Jens

Hi Jens,

Thanks very much. It did make me know some about the minix's
patitions.
Would you mind give me a further explanation? What're the 3 patitions?
During the installation, minix only ask me to appoint the size of /
home.
So there should be 2 sub patitions, / and /home. What's the 3rd one?

Thanks,
Wu

Hi, Bingzheng

I guess we should always use English when we talk about technology
stuff, for it's the de facto official language globally.

My GTalk account name is weichaoliu *AT* gmail *DOT* com. But I don't
really use instant messengers to discuss stuff. Because news groups or
forums are much more flexible that we can leisurely reply messages
when we have time so that I prefer this way.

Speaking of VMware, I'd like to use it under MS-Windows and there's no
problem if you install MINIX3 with VMware under Windows. And you can
also use QEMU under some Linux distribution. I downloaded it from the
official French website and installed it under SUSE Linux 10.3
successfully. Jorrit Herder also uses QEMU. If you wanna download
QEMU, here is the hint. You might not be able to access the official
French website of QEMU directly from China because it seems they're
blocking all the IPs from China and I have no idea why... But you can
browse it through an online proxy website.

I totally understand your mentor's opinion. It's actually more
practical to install and test it on a raw machine. But I was not
saying install it on a virtual machine (VM) for that purpose. I meant
you could read the source code, write things, debug programs and do
all the other R&D stuff simultaneously when you are running MINIX3 on
a VM. And also, the tools under MINIX3 like emacs are not as powerful
as the ones on a Linux box. I guess you know what I mean :-)

Besides, using the pre-installed MINIX3 is a good choice. You can
install all the other packages with source code when you are in MINIX.
It's just an easy command and you just need to insert the MINIX3 CD or
load the iso file of that disk if you wanna add any other
applications.

Best regards,

Hi, Sean Bray

Thanks for the advices. I will try to install minix on virtual machine
and raw one both, before the GSoC begins. I am trying the QEMU. I
found it from Ubuntu's source, it's very convenience to install it.

I fix minix's network by ifconfig just now. It's really simple. I can
ping other hosts in the same sub-net, but not the out ones. I think it
must be the gateway. But I don't know how to set the gateway yet. Can
you help me?

Thanks,
Wu

Hey Wu,

From the top of my head:

route add default gateway

Otherwise, try 'man route' to read route's documentation.

Jens

I thought they were /, /home and /usr, but I'm not entirely sure right
now. I'll look into it when I got my hands on a Minix machine.

Hi Jens,

Thanks, I just got to know that. They are /, /home and /usr. Thanks
very much.

Besides, I have resolved the gateway also, thank to Sean's help. It's
'add_route'.

Thanks,
Wu
